How can i link my mesh
The closest I came to what you probably want is this:



First, you need a new master mesh, because yours is not aligned to one of the main axis. So, create a new one. I used a simple little plane.

Now, link all meshes as you did before. And also as before, all meshes will look at the same direction as your master mesh.

Next, add an empty at the center of your Icosphere. This will be the look-at point for all meshes. So add a Track To constraint to one of them, select your empty as target, and switch To to Z and Up to X.

Last, select all your meshes with the constrainted one as active, and Object > Constraint > Conpy Constraints To Selected Objects.
